From the Environmental Health Institute in Singapore, Vincent speaks with Director Lee Ching Ng about their work to control viral infectious diseases, including the controlled release of mosquitoes containing Wolbachia endosymbionts to inhibit viral transmission.

The TWiVniks explain how the three-dimensional structure of the giant Cafeteria roenbergensis virus suggests a new mode of assembly, and the apparent elimination of dengue fever in an Australian city by release of mosquitoes harboring Wolbachia.

Sharon and Scott return to TWiV for a Zika virus update, including their work on viral evolution and spread, and whether pre-existing immunity to dengue virus enhances pathogenesis.

Preprint servers, the structure of an antibody bound to Zika virus, blocking Zika virus replication in mosquitoes with Wolbachia, and killing carp in Australia with a herpesvirus are topics of this episode hosted by Vincent, Dickson, Alan, and Kathy.
